Update 3/24/08 -- In addition to topping 16,000 full members over the weekend, we rolled out a whole new slab of features and improved, including (but not limited to):
Member Profiles: We've adjusted the placement of items on profiles pages to use available space much more effectively, and we'll be offering even more flexibility on the layout of this page in upcoming releases (You'll be able to put just about any component anywhere, very soon). Plus, this release will feature new profile themes for you to choose from!
Videos: Browse more videos even easier with an improved videos page, and video detail page. You'll be able to find search and browse videos much easier! Plus larger videos if you upload a high-definition video.
Groups: Massive improvements here. Browse and search groups much easier. The groups page is also vastly improved, with Group Admins now having the ability to add RSS to the group page, group comment wall, control over who can send messages to the entire group. Be sure to check out some great discussions going on among our nearly 800 groups!
Forums: We've also spruced up Forum discussion pages. Here's the new design, featuring a new header style, smaller attachment icons and a more streamlined layout. More changes coming to the Forums in upcoming releases.
